S58 Midpipe For BMW G80 M3, G82 M4, G83 M4 Including Competition - ARM MotorsportsThe ARM S58 Midpipe upgrade is engineered to unlock the aggressive exhaust character of your G80 M3 or G82 M4. By removing the secondary catalytic converters and the two center resonators, this midpipe significantly enhances the sound of your S58 powered BMW. At the same time, it retains the factory muffler, so you can still control the exhaust valveskeeping them closed for a quieter, refined tone or opening them for maximum volume and performance

The ARM S58 Midpipe upgrade is engineered to unlock the aggressive exhaust character of your G80 M3 or G82 M4. By removing the secondary catalytic converters and the two center resonators, this midpipe significantly enhances the sound of your S58-powered BMW. At the same time, it retains the factory muffler, so you can still control the exhaust valves—keeping them closed for a quieter, refined tone or opening them for maximum volume and performance sound.

Enhance the Sound of Your S58

The ARM S58 Midpipe not only increases overall exhaust volume but also transforms the tone into something far more distinctive than a standard G80 M3. It also makes the signature exhaust burbles more noticeable, even with the factory tune.

The G82 M4 featured in the video below is equipped with both the ARM S58 Midpipe and ARM S58 Downpipes. When paired together, the midpipes and downpipes deliver an even louder and more aggressive exhaust note compared to running the midpipe alone.

Highlights

  • Exotic exhaust sound

  • X-pipe design

  • Compatible with OEM underbody brace

  • 3-inch piping design

  • Constructed from SS304 stainless steel

  • Reduces weight by approximately 15 lbs compared to OEM

CONSTRUCTION
The ARM S58 Midpipes are a3" designfrom the downpipe connection all the way to the rear section where it will reduce to 2.75" to perfectly connect to the OEM muffler section. The ARM S58 Midpipes start with a OEM-style 2-Bolt flange which can mate up to either the OEM downpipes, or upgraded downpipes that fit the OEM exhaust. These flanges will accommodate the OEM midpipe gasket perfectly. Alternatively, you can choose to upgrade your S58's crossover pipe with the ARM S58 Crossover Pipe. The optional ARM S58 Crossover Pipe replaces the heavy OEM pipe to open up more sound and saves an additional 4lbs.



The ARM S58 Midpipe then transitions to the X-Pipe section of the exhaust via the slip-fit connections on either side. The X-Pipe is the heart of the ARM S58 Midpipe and is where the magic happens. The sound waves of each bank of your S58 engine are combined to produce a much more exotic and richer exhaust note. The X-Pipe section lives above the OEM brace with ample clearance, there is no need to install a larger brace.

From the X-Pipe section the ARM S58 Midpipe upgrade transitions back to the OEM muffler, which allows full use of the OEM exhaust valves. This gives you the freedom to choose between open and closed exhaust flaps, controlling the volume your G80 M3/M4 produces. To get a look to match your ARM S58 Midpipe check out the ARM S58 Exhaust Tips. 



The ARM S58 Midpipe will secure to the exhaust hanger on the driver's side using a standard exhaust hanger prong. It is secured to the passenger's side using the OEM style mounting bracket. These help the exhaust from jostling around during aggressive driving.

My Dog's All-Time Favorite Toy
Color: Pink, Style: Grunt Sound
The first one of these I ever got her was at Petco on sale for $1 - best $1 ever! The reviews are right, though. The toy doesn't last forever and it's not good for aggressive chewers. In my opinion, however, that doesn't make it a bad toy. Here's why: Aggressive chewers comments: Getting my sister's French Bulldog a stuffed toy (that's shredded in 5 minutes), compared to my Pitbull who does not tear up any toys, but is a stronger chewer when it comes to bones. My pup does not tear this up at all, but my sister's dog would. My point is: Don't get your dog a soft toy if your dog ruins soft toys. Regarding the not long-lasting comments: the honking noise mechanism inside eventually pops inside the hole, rendering it honkless. Ours lasted about 6 months. It's pretty much impossible to fix unless you want to trouble yourself to fix it for 1 good honk each fix. I would, but I do also have a job to get to. My dog does still carry it around in it's noiseless state, but she doesn't play with it with the same enthusiasm. How did I resolve this? I bought her 5 😂 She's only on her second, but I decided to stock it because they were on sale for $5.10 - I don't think I will get rid of any of them. I will just let her play with them on rotation until they fall apart. Besides all that, my dog just simply loves this toy. I have never seen her so happy & playful with a toy. I can't promise this for your dog, as I can only tell you about mine. We even have a "Sheepy" song. [I have not been paid or given free Sheeps - my Sweet Pea just really loves her Sheepy]

Loud! Just Like She Likes It
Color: Hedgehog, Style: Big Squeak Hedgehog
My Great Dane loves this noisy toy. She prefers squeaky toys with loud, unusual squeakers. (I need to invest in earplugs.) She's not an agressuve chewer or rough player so this should last a long time. Like most squeaky toys she has, the squeaker wears out before the physical toy does and once the noise is gone she won't play with it any more. If others have a similar issue...check with your local animal shelter. Some (not all) will disinfect used toys for the dogs in their care.

Fun while it lasts…
Color: Pink, Style: Grunt Sound
Fun while it lasts. Doesn’t last very long. This is our third one and last maybe a few weeks. The part that makes noise comes detached inside which causes to toy to no longer make noise, but also can be dangerous if it comes out.

Great alternative to the grunting pigs!
Color: Pink, Style: Grunt Sound
We go through A LOT of dog toys at my dog based business. The grunting pigs are super cute, but they are also super fragile. It is incredibly easy to dislodge the squeaker. (Grunter?) These are certainly not robust chew toys, but the squeaker is about 30% better at staying put than that of the pigs. It's also smaller, so it's easier for the smaller dogs to play with. These are a new favorite! Update: August, 2024 I bought an orange hedgehog. Amazon won't let me review that separately so I had to add to my sheep review. The orange hedgehog is only 3 stars. It is made of a harder plastic than the bear and the sheep. It also has a standard squeaker, not the grunting of the bear and sheep. But harder plastic DOES NOT mean that it will withstand an aggressive chewer! If your dog likes to "kill the squeaker" they will be able to do so in minutes! This IS NOT a chew toy! If you are looking for a toy for an aggressive chewer, look at the Orbeez line from Outward Hound. The other thing that makes me less enthusiastic about the orange hedgehog is that the yellow paint started flaking off immediately. I will have to scrub it all off because it looks terrible! The dogs don't care, but their owners sure do! I haven't had that problem with the sheep or the bears. The orange hedgehog is almost like it's from a completely different company!
